ALBERT EULGEBE PLANTE, OF MONTREAL,

QUEBEC, CANADA, ASSIGNOR OF ONE-HALF nnno'rnrc WATER-HEATER).

Application filed June 2,

To all whom it'may concern:

.Be it known that I, ALBERT Emlonn' PLANTE, residing at 367 Berristreet, in the city of Montreal, in the Province of Quebec, in theDominion of Canada, have invented certainnew and useful Improvements 1nter which is particularly. cheap and of simshape, so as to form theinner I circumference of the casing 1 Electric Water-Heaters; and I dohereby declare that the following is and exact description of the same.

The present invention-relates to'impr'ovements in electric'water heatersand its .main

object is to provide a device of this characple construction.- Theinvention will be understood with the aid of the accompanying drawingsin which: Figure 1 is a central vertical sectional view oftheimprovedheater,

Fig. 2-is across sectionview of Fig. 1.

Fig. 3 is a perspective viewof one of the supporting disks inside thecasing.

Like numerals of referencejindicate corresponding parts in each figure.I

In the drawin s .1 is the outer casing here illustrated as tu ular-andpreferably of an on line AA insulating. material such as porcelam,fiber,

etc. 2 and 3 are heads preferably of a cup chambers 1, said 'heads'bei'ng' each provided with an, opening 5 and connected at each end ofsaid tubular casing 1 by any suitable means, but illustrated inthedrawings as engaging a.

' thread rovided at each-endof said casing. Each 0 the heads 2 and 3'preferably has an inner circumferential shoulder 6 against which adisli'7 .of insulating material rests.

This disk 7 isof the same size as the inner and is provided centrally ofits outer face, (that is, the. face which confronts the casing 1) with aprojecting lug 8, and 9are a plurality ofcircumferential slots oropenings.

The disks 7 are also provided withtwo' concentric'channels 10 in whichfit the ends of the electrodes 11 and '12.

The electrodes here illustrated are preferably tubular in'shape and theelectrode 11 which is located inside the electrode 12 and suitablyspaced therefrom is of smaller diameter.

the disks 7 in order to form a communication between the two chambers 4.

Specification of Letters Patent.

a full, clear,

The space 13 provided between the electrodes 11 and 12 is made toregister with the holes 9 in Patented Jan. 13, 1920! 1919. Serial N0.301,350.

In any suitable part of the electrodes an electrical connection may bemade but in the accompanying drawings the electrodes are illustrated asbeing electrically connected at their lower end by means vof theterminals 14 of the Wires 15 which lead from the source of currentsupply and project through a suitable opening provided in'the head 3. Inthe operation of the invention the water preferably enters the head 3 bythe .opening'5, passes through the openings 9 in the lower disk 7through the passage 13 'formed between the electrodes 11 and 12, theopenings 9 in the disk 7 provided at the other end of said electrodes,enters the chamher 4 in the head 2 and passes-from the latter throughthe opening 5.

Supposing that the electrodes 11 and 12 are electrically connected to asuitable source of energy, the water when passing into the passage 13,willform aresistance between the two electrodes and cause saidelectrodes to' heat the water which passes therebetween. What I claim asmy invention is:

In an electric water heater, the combination of a vertical casing; upperand lower reversely-arranged, cuphaped heads fitted on the correspondingends of the casing and formed, respectively, with an outlet and an inletfor the water; a disk of insulating material seated in each head' andco-acting with the same to define a water chamber 1n the head, each diskbeing provided on its outer face with a pair of spaced, concentricannular channels, and with a projecting, annular rib between saidchannels having a plurality of slots formed vertically through it;interfitted inner and outer tubular electrodes having their oppositeends fitting 1n the inner and outer channels in said disks and definingan elongated tubular water chamber between them, said slots providingcommunication between the two first-named chambers and the last-namedchamber to permit the passage of the water through the heater; and meansfor supplying current to said electrodes to heat the water during itspassage.

Signed at Montreal, Quebec, Canada, this 16th day of May, 1919.
